What problems did early astronomers face when trying to justify a geocentric model?

• Retrograde motion of planets farther out than the Earth
• Bodies in the night sky moved from horizon to horizon making people think the Sun was the center
• No observations of bodies in the night sky were observable to make any logical conclusions about celestial orbits
• The lack of evidence for stellar parallax
